Creates id and idn attributes.


## Description


This is more optimized than [sop/attribCreate](/docs/nodes/sop/attribCreate) to create id and idn attributes, although the attribCreate node can create them similarly using the following expressions:

`@ptnum` for the id attribute
`@ptnum / (pointsCount(0)-1)` for the idn attribute
